THRASHING MACHINE.

Application filed August 20, 1921. Serial No. 493,890.

11y vegetation in such manner that the latter will be left standing after the thrashing operation and ready to be turned under whenever desired, thus obviating the work of cutting, shocking, stacking, and subsequent thrashing, in the manner now customary in present day practice. More particularly stated, the invention relates to improvements in thrashing machines such as described in my prior Patent No. 1,379,112, issued May 24, 1921.

The primary object of the present invention is to improve, with a view to increased efficiency, the construction, arrangement of parts, and operation of the machine disclosed in this earlier patent, particularly with regard to the thrashing mechanism,-

the adjustment of the latter and related parts to accommodate vegetation of different heights, and the grain-collecting and conveying means.

Other objects of the invention will appear from the following specification, taken in connection with the accompanying drawings, wherein one form of the invention is illustrated.

Fig. 7 is a detail view showing` the lock ing pawl for the hoisting mechanism;

Fig. 8 is a side elevation of the rear of the machine, showing the drivers seat and steering mechanism;

Fig. 9 is a detail view of the conveyor driving shaft;

Fig. 10 is a side elevation of the machine showing the raising and lowering mechanism and related part-s in detail, many of the other parts being omitted;

Referring more in detail to the drawings- 5 is a section on the line 5-5 vof 10 designates the two forward supporting or traction wheels of the machine, one of which carries a driving element in the form of a large sprocket wheel 11. The wheels 10 are mounted on the opposite ends of an arched axle 12, which supports or carries substantially the entire weight of the machine. Mounted in suitably spaced relation upon the raised horizontal portion of the axle'12 are a plurality of upstanding bearings 13 and 14, the former supporting'a transverse shaft 15 and the latter an oscillatory or tiltable frame 16. rlhe shaft extends only part way across the machine, and is provided adjacent its outer end with a sprocket lwheel 15a, through which and the drive chain 17 the shaft is driven from the main drive sprocket 11, previously described.

The tiltable frame 16 is made up of a plurality oflongitudinally extending beams or angle irons 16, properly reinforced by struts or the like 16a extending longitudinally of the machine and by transverse beams' 1Gb, which may also be of angle iron construction. As previously pointed out, the tiltable frame is pivotally mounted on bearings 14, which extend up from the hori`-` Zontal arched portion of the axle 12. The frame, at its forward end, carries a transverse shaft 18 mounted in suitable bearings carried by the longitudinal beams of said frame. Keyed to the shaft 18, and adapted to rotate therewith, are a plurality of thrashing wheels 19, which are properly spaced transversely of the machine, in order to pro-vide a plurality of thrashing zones, as will be more particularly hereinafter described.

Suitable cables 16c or the like are attached at one end to the rear of the frame 16, their other ends being attached to a transverse hoisting shaft 20, the latter being suitably mounted in bearings mounted in the side walls 21a of the box 21, which latter extends rearwardly of the axle 12 and which houses the rear portion of the conveying mechanismthe grain-elevating mechanism, and the storage bin, as will be hereinafter more fully pointed out. The box 21 is mounted on a rearwardly projecting frame 22, carried at its forward end by the axle 12 and at its rear end supported on the forward end of the pole or shaft 23, the latter, in turn, being supported by the small steering wheel 24 at the rear of the machine. From this it will be apparent that the box is stationary,

or, in other words, not movable with respect to the axle. rlhe hoisting' shaft 20, being mounted in the bearings in the side walls of the boay 21, is likewise stationary, and hence upon rotation, through a suitable hand wheel 20a or the like, the frame 16 will be oscillated or tilted about its pivots in suchwise as to raise or lower the outer end of said frame, as will be readily understood. The rotation of the hoisting shaft may be controlled, if desired, by means of suitable ratchet and pawl mechanism, such as shown in Fig. 7 'of the drawings.

The thrashing` wheels 19 (four being` shown in the drawings by way of illustration) comprise a plurality of radially disposed fan blades 19a, suitably reinforced by spoke-like members 19h. Each of these thrashing-wheelscarries on its operating side a plurality of spaced apart thrashing elements 19C, the latter being shown in the form of loops' and preferably formed from small strips of metal bent into substantially U shape and flanged at their free ends for attachment to the fan blades, as shown. Each of the thrashing' wheels shown in the drawings is provided with three series of these thrashing elements, said series being disposed concentrically upon the wheel.

The thrashing wheels 19, upon operation of the machine, coaet `with stationary thrashing members 25, there being three of these members shown in the drawings, one for each of the outside thrashing wheels, and one center or intermediate member which is common to both the intermediate thrashing wheels. rilhese stationary thrashing members are pivotally mounted on the oscillating frame 16, adjacent the outer end thereof, the supporting bearings 25EL being carried by the longitudinal beams 16d. As will appear from the drawings, these members '25 are swung from the frame 16 in suoli wise as 'to cover the lower portions-of the thrashing wheels, said members being mounted in rather close proximity to the active faces of said wheels, but spaced sur'liciently therefrom to provide 'for a slight clearance between the ends of the thrashing elements or loops 19C and the adjacent face of said members upon rotation of said wheels. The members 25 are shown in the drawings as constructed of metal and as being of double. wall construction, but this need not be, as these members may, obviously, be constructed of other materials and of different` designs. Mounted on the outer face of each of the outside stationary members 25 are a plurality of thrashing elements 25C, substantially the same in design as the thrashing elements 19C carried by the wheels 19. The center stationary thrashing member also carries a plurality of thrashing elements 25, these, however, being disposed on both sides of this member and designed to cooperate,

respectively, with the two intermediate thrashing wheels. In other words, the center stationary thrashing element 25 is common to the two intermediate wheels 19. rlhe thrashing elements 25C are also arranged in series properly spaced apart, and each series is in the form of an arc concentric with respect to the shaft 18 and are designed, upon operation of the machine, to project between the series of thrashing elements earried by the thrashing wheels, as more clearly appears in Fig. 5 of the drawings.

Suitably supported from the lower edges of the stationary thrashing members or boards are conveyor troughs 26. The lateral areas between the outer thrashing wheels and their adjacent stationary thrasl ing boards and the space between the two intermediate thrashing wheels and the center stationary board are termed thrashing Zones. The conveyor troughs 26 extend long'tudinally of the machine from a point well. in advance of the thrashing wheels to a point in arrears thereof, and throughout their length underlie the thrashing Zones j ust described.

The troughs 26 are adapted to catch the grain or seed as the latter is removed from the standing vegetation during the thrashing operation, and, in order to eliminate any possible waste, the saidtroughs are provided with outwardly flared side walls Q'Gl. A pair of channel beams 25 are mounted in each of the conveyor troughs and extend from the front end of the latter to the rear thereof, the rear ends being secured in any suitable manner to a transverse angle bar 2T and throughout their length at suitable intervals, by means of metal straps or the like 27, to the lower edges of the stationary thrashing boards llhe channel beams 25h are mounted with their channels disposed inwardly, so as to provide a suitable housing` and support for the endless chain conveyors 28, the latter con'iprising sprocket chains Q8, having mounted thereon at suitable intervals brushes or the like 28h. 'lhe chains 28 enidle sprocket wheels QSC, mounted on suitable sha its journalled adjacent the 'front ends of the channel beams 2li, and sprocket wheels 28 keyed to drive shaft 2S extending` transversely of the machine and suitably jonrnalled in the beanis adicent the rear ends thereof. The drive ft 28@ is, preferably, of sectional construction, as shown more clearly in Fig. 9, each section being loosely pinned to adjacent sections so as to permit of a certain amount of free play, to avoid binding, twisting or breakingv of the shaft when the machine is operatingl over uneven ground.

A substantially L-shaped bracket is rigidly mounted on the angle bar 2T at the rear ofthe center conveyor trough, this bracket extending rearwardly from its point ot attacl'uuent and upwardly, substantially as shown in Fig. 3 of the drawings. At its upper end this bracket is provided with two journal bearings Q9 and 29", the former eX- teiiding transversely with respect to the longitudinal axis ot the machine and the latter extending longitudinally of the machine, but being slightly inclined with respect to said axis. A relatively'short shatt 30 is mounted in the bearing 29h, and upon the rear end of this shatt is mounted a grain elevator wheel 3l. rlhe other end ot the shaft is provided with a bevel gear 30, which meshes with a bevel gear 32, mounted. on the correspondingl end ot the shatt 82 journalled in the bearing 2U. This latter shaft is also supported adjacent its other end by means ot a bracket Z133, similar to the bracket 29, previously described. VYflic bracket 33 is also mounted on the angle bar 2T. The outer end ot the shatt 32 is provided with a sprocket wheel 32", which is operatively connected with the sprocket wheel 34 carried on the corresponding end oit the conveyor drive shaftt 28C by means ot a sprocket chain 85.

The elevator wheel 31 comprises a suitable hub portion, which is carried by the outer end olf the inclined shaft 30, previously described, and radiating from the hub are a plurality et arms 31, the latter bein r provided at their ends with scoops or the like 81". Suitably secured to the under portion ot the machine and partially enclosing the elevator wheel, a sheet metal drum 36, said drum closely `titting the wheel 31 in such ".vise that upon rotation thereot' the scoops 51 will coact with the inner periphery ot the drum in elevating the grain or seed, in a manner hereimrtter described. rlhe front portion ot the drum underlies the rear ends ot' the conveyor troughs, and the bottom ot the drum extends below the bottoms ot said troughs, so as to torni, in etlect, a receiving pocket 3G for the grain as the same is swept rearwardly through the conveyor troughs. rllhis pocket is common to all ot the conveyor trough y and accordingly all of the thrashed grain or seed is deposited in this pocket.

YUpon operation o'trthe machine the grain as it is deposited in the pocket 36 is picked up by the scoops 31 ot the elevator wheel, the latter being geared to rotate at such speed that the grain may tall by gravity 'troni the scoops during` their travel across the upper portion olf the drum. On each arm ot the wheel, iniediately beneath the scoop at'tho end ther-cot, is positioned an inclined detlector plate 31, and the rear wall Btl" ot the drum 36 which, as will be obsewed, only covers substantially the lower halt ot the wheel 31, is also provided with a plate SGC in the torni ot a downwardly turned tiange along its upper edge. rlhe grain, as it talls 'from the scoops 31b in the manner just described, is deflected by the.

plates 31C and 3G rearwardly ot the drum and into a suitable bin or storage receptacle 37. ylhis bin or storage receptacle. is mounted on the rear stationary frame 22, previously described, and is enclosed,.save for its top, by the box or body 21, also previous ly described. lllounted across the upper end ot' the bin is a screen 87a, the latter beino slightly inclined, as shown, and adapt-- ed to screen from the grain or seed, as the latter is deposited in the bin, all 'foreign material, such as straw, weeds, and the like, the latter being easily removed through the opening 3S provided in the rear wall of the boi; 21. The bin 37, being mounted on the stationary traine 22 of the machine,is spaced sutliciently trom the rear wall 36D ot the drum 36 to permit the movement ot the latter upon oscillation ot the tiltable trame 1G. It will be appreciated from the foregoing that the conveyor troughs and associated mechanism and elevator wheels, its drum and driving connections, are all raised or lowered upon oscillation o1 the frame 1t by means et the hoisting cables previously described, this being due to the tact that all oit these portions ot the machine are surpended Yfrom the front end ot the` 'trame 16 through their connections one to the other, and ultimately to the stationary thrashing boards 25, which are pivoted to the traine immediately beneath the shalt which carries the thrashing wheels.

Suitably secured to the stationary trame 22 ot the machine and exteriorly oit the bonY 21 is an upstanding bracket 39, carrying at its upper end a transverse shaft 39 having mounted thereon two sprocket wheels 39 and 39, the former being operatively connected to the shaft 15 by means oit a sprocket chain l0 and sprocket wheel 15b, keyed to sait. shaitt. rlhe sprocket wheel 39C is operatively connected to the conveyor' drive shat't 28@ by means ot a sprocket chain 41 and sprocket wheel 112, keyed to said shaft. The shaft 15 is also provided with a sprocket wheel 15C adjacent its inner end, this sprocket wheel being operatively connected to the shaft 18 by means ot a chain llt-3 and sprocket wheel 18a. its previously described, the shaft 32 is operatively connected by.. means ot sprocket and chain to the conveyor drive shaft 2SC.

From the Yioregoing description et the power-transmitting mechanism ot the inachine, it will be apparent that upon nievement ot' the latter power will be transmitted to all of the driven elements oi the entire mechanism from the main drive sprocket 11. il. suitable clutch GO is mounted on the shaft 15 immediately adjacent the sprocket wheel 15, and may be operated by means ot a lever G1, to render the parts operative or inoperative during the movement ot the machine.

Mounted on the stationary frame 22 ot the. machine, directly opposite the bracket Si), is a braclvt dit, ot substantially the sain` construction as the bracket This braeliet si also carries atits upper end a transverse shaft da, and extending between this sha'it and the conveyor drive shaft 28@ is a radius rod 45, this rod being pivoted at one end to the shaft and to the Correspending` end ot the conveyor drive shaft at its other end. At the other side oi' the machine au other radius rod @l5 connects the shaift 89 with the other end ot the conveyor drive shaft. The. brackets 39 and i4- being' stationary, and the conveyor drive shai't QSC being movable upon oscillation ot the tiltable trame 1G, it will be observed that the radius rods will function to prevent undue separation ot the elevator wheel and associated parts trom the bin 3T when the irame 6 is adjusted. in other .vords, the rear end ot the movable or adjustable portion ol` the machine is maintained operatively disposer` with relation to the rear stationary portion the machine by means olf this radius rod construction. rflics-e r dius rods aiso serve to n'iaintain the conveyor troughs in a more or less horizoiital plane, regardless et the position into which thn trame lt is adjusted. r.this will be appreciated when it is ien'ienibered that the stationary thrashing; boards 25, 'from which the conveyor mechanism and associa ed elements ot the construction are suspended, are pivotally swung trom the end of the frame lo.

Projecting' forwardly ot the machine from the front ends oit the conveyor troughs are a plurality of cone-shaped separators or dividers liti, these devices being; adapted to separate the standing' vegetation into rows as the machine is moved forwardly, and to `guide the vegetation thus separated into the thrashing' zones, will be understood. ri`hese dividers liti are provided with upwardly inclined tin-lil-e portions d6 which extend rearwardly and are attached, respectivelv, to the upper 'front corners oi" the statioi' ,ry thrahing boards lying immediately to the rear thereof. rEhe portions ot the dividers i6 which overlie the :trent ends oi Vthe conveyor trough are cut awayj as at in order that any grain falling; in advance oi'iathe thrashing mechanism will be caught by said troughs.

A cross beam di, suitably reinit'orced, is supported slightly in advance oi the trame 16 and above the thrashing; wheels 19 by snitable rods or other supporting members which are mounted on the lonnit-ud al members ot the trame i6. Suj'iported Yiroiu this cross beam and above the dividers #it are a plurality o'l auxiliary cone-shaned dividers 4F, these being' designed to aid in the separation 01"' the grain. rilwo forwardly projecting beams 48 are pivoted at 48d, one

Locali-5e on either side ot the machine outside of the thrashing mechanism, 'these beams being supported near their outer ends by means ot' the stay rods L18 connected to the cross beam 47. rilhroueh these connections these beams 48 are raised and lowered with the frame 1G, the cross beam 17, as previously described7 being` supported by rods mounted on said trame. At the outer end of the beams 48 vwing-like elements 4S" are disposed, and eX- tending` rearwardly from these elements are a plurality of guide rods 48C, these rods and the elements 48" being designed to cooperate with the outermost dividers i6 and 7a in separating the vegetation and in guiding' the same to the outermost thrashingY zones. The auxiliary dividers it?" are also preferably supported from the cross beam i7 by means of adjustable straps 47 or the like, so that,y ii desired, tue position oi said dividers may be varied with respect to the main dividers ALG.

yihe shajtft or pole 23 at the rear ot the machine is supported by means of the small steering wheel 2li. This steering wheel is provided with an upwardly extending post suitablv mounted and provided at its upper end with a` hund wheel 49. A drivers seat 50 is mounted at a convenient point adjacent the steering wheel. An evener 23 1s mounted on the pole Q3 in advance ot the steering' wheel, to which the draft animals may be hitched for propelling the machine during' the thrashingr ooeration. lt will be 'eadily appreciated, however, that modilicaion ot the machine may be effected to acco-.'nnodate motive power in the form ot' a tractor or the lilie without departingv from the spirit or scope of the invention.

l the operation oif the machine the frame iii-st adjusted to accommodate the vegetai n to be cted upon. The machine is 'then pushed Yforward into the vegetation, and as this is done the dividers at the torward end thereoit separate the vegetation into rows, tour in number in the present machine, and these rows o'l vegetation are then guided into the respective thrashing Zones, where each stall; is violently shaken in a lateral direction by the looped thrashing;` elements carried both by the thrashing;` wheels and the stationary thrashing` boards. This violent shaking` of the stairs of grain results in the separation ot the l(train therefrom, the same 'la ling' downwardly into the conveyor troue'hs which underlie the thrashing` Zones. its above described7 each thrashingv wheel comprises a plurality ot i'an blades. These tan blades are so arranged that upon rotation oit the wheels currents ot air are set up by each ot the wheels in the direction ot their respective stationary thrashing' boards, Much ot the grain which would otherwise be lost is caught in these currents of air and blown against the adjacent stationary board,

lll() which latter detlects the same downwardly and into the collection troughs. In the collection troughs the grain is moved rearwardly by means of the endless conveyors, and is deposited in the pocket 36 at the rear of said troughs. From this point it is elevated by the elevator' wheel and deposited in the stationary bin or sto age receptacle at the rear of the machine.

Although I have shown and described one particular embodiment of the invention for purposes of illustration, it will be understood that it may be constructed in various other forms without departing from the scope of the invention as defined in the appended claims.
